I just installed a new motherboard, but I couldn't connect the ribbon-y IDE cable to the motherboard because it's an SATA only motherboard. I know you can get an adapter for this, but I want to know if this effects the running of the computer, because ever since installing my new parts, (CPU, Heat Sink, Motherboard, and RAM), I cannot get past Windows beginning to boot. I cannot install Windows again either. BIOS does work. So basically, could having an unattached IDE cable effect the running of my PC? Is it necessary to have it? Thanks.
